Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Run ollama pull <model> on the server that base_url points to, or use an exact name from the "Available local models" list (including tag).
Option: Pull the model on the target server or use the exact tagged name [evidence: official_recommended_action]
Applies when: validate_model_on_init=True
Steps:
1. ollama list on the host behind base_url
2. ollama pull <model:tag>
3. Use that exact name in ChatOllama(model=...)
Expected: Validation passes
